6 years ago We came up with a sample query:
SELECT DISTINCT ?Name ?Address ?Description ?Longitude ?Latitude (year(?inception) as ?TimeStamp)
WHERE {
SERVICE wikibase:label {
bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en".
?band rdfs:label ?Name .
?band schema:description ?Description .
?place rdfs:label ?Address.
}
?band wdt:P136 wd:Q3071.
?band wdt:P31 wd:Q215380.
?band wdt:P740 ?place.
?place p:P625 ?coordinate.
?coordinate psv:P625 ?coordinate_node.
?coordinate_node wikibase:geoLatitude ?Latitude.
?coordinate_node wikibase:geoLongitude ?Longitude.
?band wdt:P571 ?inception.
}download as CSV and upload to Geobrowser is possible.

Idea:
There are already different applications available that allow to visualize spatio-temporal data from Wikidata e.g. ViziData (https://github.com/arsylum/ViziData),
https://tools.wmflabs.org/wikishootme/#lat=51.539937099999996&lng=9.936693199999999&zoom=15,
https://tools.wmflabs.org/wikidata-todo/tempo_spatial_display.html,
https://tools.wmflabs.org/wikidata-todo/missing_images.html
The SUB has with the DARIAH-DE Geo-Browser (https://geobrowser.de.dariah.eu/, https://github.com/DARIAH-DE/PLATIN) an explorative tool for spatio-temporal data. The Idea is to make spatio-temporal data from Wikidata available with the Geo-Browser. This means creating a tool that allows to predefine Wikidata queries and that converts the result sets into Geo-Browser specific data format (https://www.dropbox.com/s/httk62myn2tsi4p/M3.3.2_eConnect_KML_Specification_v1.0_UGOE.pdf) and visualize them afterwards.
One option is to start with an application that offers a graphical query-builder. The Wikidata-SDK (https://github.com/maxlath/wikidata-sdk) could be reused to generate the result sets. A conversion functionality has to be created to bring the query results into a Geo-Browser conform data format. The final data can be visualized with the Geo-Browser.
Further possibilities:
Adding a “Add Wikidata identifier”-Button to the Datasheet Editor (https://geobrowser.de.dariah.eu/edit/index.html) Could be realized as a mapping between Geonames and Wikidata (see https://opendata.stackexchange.com/questions/3728/mapping-between-wikidata-and-geonames/3731)
